WRENCH.

Application filed February 9, 1922. Serial No. 535,268.

To (ZZZ whmait may concern:

Be it known that I, MARTIN a citizen of the United States, and a resident of Columbia Falls, in the county of Flathead and State of Montana, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to wrenches, and

more particularly to ratchet wrenches of the v kind employing a brace, and the object thereof is to provide a wrench having a brace of novel shape or formation so as to especially adapt the same for use in connection with the nuts of the fourth connecting rod of a Ford car, or the like, although it is obvious that the device may be used wherever practical in inaccessible places.

Other and further objects of my invention will. become readily apparent to persons skilled in the art, from a consideration of the following description when. taken in conjunction with the accompanying drawings, wherein: a i a Figure 1 is an elevation of the improved wrench.

Figure 2 is a face, view'of the wrench head or socket, and

Figure 3 is a sectional view taken on the line 3--3 of Figure 1..

Referring to the drawings in detail, in which like. reference characters designate corresponding parts throughout the several views, my improved device is shown as comprising a sweep or brace 10 consisting of an axial portion or stem on which'is mounted a swiveled knob or handle 12, the latter being preferably of wood and having a metal bearing and sleeve connection 13"by which the same is adapted to be held stationary while the sweep is operated by oscillating or working the same back and forth,

or rotating it where such is possible. The.

sweep or brace 10 is formed of a bar or section of metal of suitable strength such as steel, and is extended outwardly at an obtuse angle but substantially at right angles to the stem or shank 11, as indicated-at 1 1 and the bight or gripping portion thereof is then extended substantially at right angles but parallel to the shank or stem 11,

as indicated at 15, anc then at an obtusev angle so as to diverge from the portion 1% substantially at right angles to the portion 15, as indicated at 16, the divergence from New mm tt angular extension.

the connecting portion or bight 15 017 the. convergence of'the'portions 14 and 16 'toward the bight or connecting portion 15 ac'-' commodating the hand'during the use of the wrench. The sweep 10 as thus constructed is of U-shaped form, the portion 15 constituting the body of the sweep, the portion 14 the long leg thereof and the portion 16 the short leg thereof.

At a point spaced from the axis of the shank-or stem 11, the portion 16 is bent parallel to the portions 11 andl5, a short distance, as indicated at 17 and then at right angles toward the axis of said shank or stem 11 as indicated at 18 where it is provided with a reversible ratchet construction 19 consisting of a reversing ratchet sleeve or dog 20 having pawls 21 co-operating with the ratchet teeth 22, as is well known in the art. The portions 17 and 18 constitute an The head 23 of the wrench is provided. with a socket 24- for accommodating a nut, the same being of hexagonal or other shape, but especially hexagonal for use in connection with the fourth connecting rod of a Ford car. By this construction, the socket can be readilyapplied to the connecting rod cap nuts which renders them easily accessible from the bottom portion of the motor by removing the crank case at the bottom, or the plate thereof, so that the nuts may be either tightened or loosened by working the sweep or brace part forward or backward by oscillating the same through the medium of the ratchet mechanism. By reversing the position of the sleeve, the ratchet device may be reversed so that the nuts may be loosened or tightened as desired.

The advantages of this design of a wrench is that after it is adjusted to the nut of the fourth connecting rod, it canbe held in perfect alignment with the nut under themost severe conditions while the same is being turned off or on. The long sweep with the knob to support the same gives the user great leverage which is very important in a wrench for this purpose, the knob or han-- 'it will reduce the cost of having the connecting rodsadjusted at least one-half, and the work will be a pleasure instead of a source of much energy and bruising of axially alined and having swivelled connec tion With the handle, said sweep also having a short leg provided With an angular extension including a portion extending parallel to :the axis of the handleand socket and a portion extending at right angles from the outer end of said first mentioned portion and toward the common axis of the handle and SOCkBtfZIDCl a ratchet connection directlyconnecting the outer end of the last mentioned portion of the angular extension and the socket.
